Value Collection 151262PR Set Screw 5/16-18 X 3/8 in Flat Point

Product Description

The VALUE COLLECTION 151262PR is a flat point set screw designed for secure, non-marring fastening in mechanical assemblies where a flush or recessed holding force is needed. Threaded 5/16-18 UNC and measuring 3/8 inches in overall length, this headless fastener is driven with a 5/32-inch hex key. It is manufactured from Grade 8 alloy steel, providing high tensile and torsional strength suitable for demanding industrial and maintenance applications. Machinists, millwrights, and maintenance technicians commonly install these screws to secure collars, hubs, pulleys, and similar components to shafts without damaging the mating surface.

This set screw is suited for use in light industrial, manufacturing, and general mechanical maintenance environments. The flat point distributes clamping load evenly against the mating surface, making it a common choice when shaft marking or deformation must be minimized. Conforming to ASME/ANSI B18.3 and ASTM F912, this fastener meets widely recognized dimensional and mechanical standards. It is appropriate for applications requiring a high-strength headless fastener in standard fractional-inch UNC thread configurations.

Key Features

• 5/16-18 UNC thread for compatibility with standard fractional-inch tapped holes
• Flat point design minimizes marring or deformation of mating shaft surfaces
• Grade 8 alloy steel construction delivers high tensile and shear strength
• 5/32-inch internal hex drive for use with standard hex keys or Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• 3/8-inch overall length suits shallow-thread engagement applications

Compatibility

Designed as a standard 5/16-18 UNC flat point set screw for use in any tapped hole conforming to ASME/ANSI B18.3 specifications, including collars, shaft hubs, pulleys, and mechanical assemblies requiring a headless fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/32-inch hex key or T-handle driver. De-energize and lock out any rotating equipment before installing or removing set screws. Ensure the tapped hole is clean and free of debris before threading in the screw. Apply appropriate thread-locking compound if vibration is a concern in the application.
